The effects of Sc and Zr element on the recrystallization behavior and microstructure evolution of Al-Mg alloy had been researched in this paper, and meanwhile, the microstructure and mechanical properties of the friction stir welding joints were also analyzed. The results show that the recrystallization and grain growth behavior of Al-Mg-Sc-Zr alloy can be inhibited effectively by microalloying with Sc and Zr. Compared with Al-Mg and Al-Mg-Zr alloys, the recrystallization start temperature and finish temperature of Al-Mg-Sc-Zr alloy increase significantly, and the strength of alloy sheet which subjected to stabilizing annealing is increased by more than 50MPa. Moreover, the recrystallization softening effect of the welded joints microstructure, which caused by the welding temperature field and welding heat input, can be weaken by microalloying with Sc and Zr, the width of recrystallization zone is reduced, the microstructure and properties of the welded joints are improved. The friction stir welding coefficients of Al-Mg-Sc-Zr alloy increases to 86.9%.

The precipitation of T1 phase during the ageing of an Al- Li- Cu -Zr alloy sheet was studied by DSC (Differential Scanning Calorimetric) technique. Results showed that precipitation of T1 phase occurred in temperature range of 250°C to 300°C whereas its dissolution occurred within the temperature of 450°C to 530°C. Furthermore, activation energies for precipitation and dissolution of T1 phase were determined 122.1 kJ/mol and 130.3 kJ/mol, respectively.

The coating preparation of HA on the surface of Mg-4.0Zn-1.0Ca-0.6Zr alloy sheet is carried out through a technique combining of pre-alkali-heat-solution-treatment, electro-deposition and post-alkali-heat-solution-treatment. The microstructure and appearance of the coatings are observed and analyzed by means of scan electron microscope. As well as with help of spectrophotometer, the antihemolytic ability of the alloy with HA coated in blood has been studied. The results indicate that the available ageing treatment of the alloy sheet is at 175 °C for 12 hours, and as the rule, the yield strength σ0.2 and elongation rate δ % is reached 320 MPa and 18.75 % respectively. The HA coated with a desirable microstructure is achieved under the technique parameter of the temperature 50 °C and the voltage nearly 10 V, as well as it’s ratio of Ca and P is 1.72 which is close to the human bone tissue of 1.67. The concentration of [Mg2+] in leaching liquor is depressed as the using of the alloy with HA coated so that the adverse reaction caused by higher concentration of [Mg2+] in the parts of the body position can be avoided. The value of hemolysis ratio of the alloy with HA coated is 4.06 % less than that of the alloy with un-coated which is 4.35 %, therefore the antihemolytic ability of alloy with HA coated is increased, and the phenomena of hemolysis is not taken place when it is used as one of human body planting material.
